CompactLogix System Distance Ratings
Because the 1768 CompactLogix power supply works with the controller to
power a 1768 system, the distance rating in a 1768 CompactLogix system differs
from that in a 1769 CompactLogix system.
In the 1768 system, the distance rating is the distance between 1769 I/O modules
and the controller. In the 1769 system, the distance rating is the distance
between 1769 I/O modules and the power supply.
Follow these requirements to determine proper placement of your
1768 controller, power supply, 1768 I/O modules, and 1769 I/O
modules:
• Place the 1768-L4xx controller so that it is the last module
(furthest away from the power supply) in the 1768 backplane.
• The 1768 CompactLogix power supply distributes power from
the right side of the supply and must be the leftmost module
in the system.
• Up to eight 1769 I/O modules can reside in the local bank.
• The local bank is powered by a 1768 power supply.
• Up to two remote banks of 1769 I/O modules may be
connected by using 1769-CRLx extension cables.
• Remote banks are powered by a standard 1769 power supply.
Publication 1768-IN004D-EN-P - December 2009
CompactLogix Controllers 9
• Up to eight 1769 Compact I/O modules can reside on each
side of a 1769 power supply in a remote bank. Consult the
module’s specifications for its distance rating.
IMPORTANT
Never place a 1769 power supply in a local bank with a 1768
controller or a major fault will occur.
• The type of controller determines the maximum number of
1768 modules that can reside in the local bank and the
maximum number of 1769 I/O modules that can reside in one
local and up to two remote banks.

Troubleshoot System Power
The CompactLogix power supply works with the CompactLogix
controller to provide power to the system. You must consider both
when attempting to troubleshoot system power.
IMPORTANT
Before you disconnect, reconnect, or replace any component, make sure you
have turned off power and allowed all system status indicators to turn off.
To troubleshoot system power issues, use the CompactLogix power
supply PWR status indicator and the CompactLogix controller PWR
and I/O PWR indicators. If the power supply is not operating
properly, the controller will not operate properly either. You must
first diagnose and correct any issues with the power supply before
troubleshooting the controller.
1. Examine the power supply PWR status indicator.
2. If the power supply is operating properly and the power
supply PWR status indicator is green, examine the controller
PWR indicator.
3. If the controller PWR status indicator is green, examine the I/O
PWR status indicator.
